<hr>

<p>The FastLoad Format uses a compressed ASCII format that permits files to be downloaded
in less than half the time taken for Motorola S-records. </p>

<p>The base-64 encoding used is &quot;<tt>A-Za-z0-9,.</tt>&quot;. The data is encoded in
groups of 4 characters (24 bits). The character '<samp>/</samp>' is used to introduce a
special function. Special functions are:</p>

    <table border="1" cellpadding="5" width="80%">
      <tr bgcolor="#CCCCCC"> 
        <td valign="top" align="left"><samp>A......</samp></td>
        <td>Defines an address. </td>
  </tr>
  <tr>
    <td valign="top" align="left"><samp>B..</samp></td>
    <td>Define a single byte. </td>
  </tr>

    <td>Define the program's entry point. The address will be the current address as defined

      /BAB            - byte of 01
